To all whom t may concern.'

Be it known that l, ABRAM N. PASMAN, a citizen of the United States, residing at East Orange, in the county of Essex and States of New Jersey, have invented an Improvement in Flush-Valve Apparatus, of which the following is a specification.

This invention relates to the chain pull type of flush valves employed with tanks or other receptacles commonly used in flushing toilets or other places where at certain times a predetermined flow of water is required. Heretofore various forms of chain pull flush valves have been employed. In this type of flush valve in use at one time,

uthe valve was so constructed as to open by pulling the chain and to close immediately when the chain was released, and in its use it was necessary therefore to actually hold the valve open until the required flow of water was obtained. More recently, and taking the place of this type of valve to a large extent, a siphon flush valve has been employed. The siphon valves, however, are relatively expensive, and are also likely to get out of order at frequent intervals, and the object of the present invention is to provide an inexpensively constructed iiush valve in which the iiow of the water through the same is maintained while in an open position until the water in the tank or other reservoir reaches a predtermined level when the valve automatically closes; and the invention also includes a means for regulating the Avalve to close at different water levels in the tank or reservoir for the purpose hereinafter indicated.

The flush valve made in accordance with my invention will be hereinafter more particularly described in connection with the accompanying drawings forming part of this specification, and in which Figure 1 is a sectional elevation illustrating my improved fiush valve as applied to a supply tank. Fig. 2 is an enlarged sectional view of the same. Fig. 3 is an inverted plan showing the construction of the operating parts of the valve. Fig. et is a plan of the modification shown in Fig. 5 which is a sectional elevation illustrating the means by which the valve is caused to close at different water levels in the supply tank or reservoir.

In the drawing, 10 indicates a *tank or reservoir as commonly employed to iush toilets and other` similar places where a pull chain flush valve is installed. As is customary in such instances, I employ a pipe fitting 11 passing through and fixed in the bottom of the tank. Beneath the tank a flush pipe 12 is suitably connected to the fitting 11, which at its inner end and within the tank terminates in an annular exten sion or body member 13, the extremity of which acts as a valve seat. The valve is preferably so constructed as to comprise a disk head 15 carrying a washer 16 placed between the same and the inner end 17 of the valve head. he washer 17 is adapted to seat against the extremity of the body member 13, and the inner end 17 of the head to lit within a recess 18 provided therefor interiorly at the extremity of the body member. Secured to the valve head li employ a number of radially placed blades 19,.

which are suitably connected to the valve head and adapted to it within the body member 13 so as to act as guides in the movement of the valve in the opening and closing thereof. In the drawing, three of these blades are illustrated, but it will be understood that the invention is not limited to this number. rlllhere being three blades 19 illustrated in this instance, the interior of the body member 13 is divided into com-1' partments A2O, 21, and 22 through which as it will ie understood when the valve is open, the water from the tank will flow through the body member 13 of the fitting, and the-nce to the Hush pipe 12 leading to the closet or other devices to be flushed.

Associated with one of the blades 19 so as to lie within the compartments 21 and 22, 1 employ vanes indicatedl at 23. These are pivotally connected to one of the blades 19 as indicated at 24, and are so constructed as to be rights and lefts with the corresponding sides 25, lyingv against the blade to which they are pivotally connected, while the faces 26 of the valves when the valve is open, as shown in Fig. 2, are forced by the water pressure flowing into the compartments 21 and 22, so as to lie against the adjacent faces of the other blades 19. The inner extremities of the vanes 23 are curved as indicated at 27, and the extremities of the vanes beyond their pivotal points at the opposite ends are provided with square corners or lugs 28 adapted when the valve reaches a certain point in moving toward its seat to contact with the edge defining the recess 18. Due to the weight of the valve this contact LSD has a tendency to swing the vanes in the opposite direction against the pressure of the flowing` water. Consequently as long as the water pressure is sufficient to maintain the vanes in such positions that the lugs 28 bear on the edge defining the recess 18 it will hold the valve in an open position and the water will continue to flow, this action being assisted by the curved ends 27 of the vanes. When however the water level in the tank is lowered sufficiently far to reduce the pressure to such an extent that it will no longer support the valve, the valve continues its inward movement, by gravity, until it reaches its seat, and in which movement the lugs 28 ride over the edge defining the recess 18 and the vanes assume the positions indicated in Fig. 1 of the drawing.

The disk head of the valve is connected to a tube 29 which acts both as a means for lifting the valve, and as an overflow for the tank. rlhe upper end of the tube 29 is connected to the inner end of a lever 30 by means of a chain 31. The lever 30 is pivotally mounted in a bracket 32 suitably connected to the tank or other support, and at its opposite end has attached thereto a. pull chain 33 by which the valve may be raised from its seat.

In Order to regulate the time in which the valve will close and also the consequent flow of Water through the same as well as to obviate any disagreeable noise caused by the mingling of the air with the water just before the valve closes, I may, as indicated in Figs. 4 and 5, provide the valve head with an annular rim or flange 34- made concentric with the tube 29, and forming a pocket or water chamber 35. The annular rim 3d is fitted with a sleeve 36 surrounding the same and revoluble thereon. In the annular rim 34 there is a slot 37, preferably made at an inclination as shown in Fig. 5, and in the sleeve 36 is an aperture 38. By this construction, as will be apparent the valve may be weighted by adjusting the relative positions of the slot 37 and the aperture 3S so as to retain in the pocket a predetermined quantity of water when the tank is emptied, and by so doing the valve may be regulated to seat when different and predetermined water levels above the valve seat in the tank have been reached.
